Let a = {0,1,2,3,4}×{0,1,2}, let b = {n | n is a positive factor of 144}, and let f : a→b with f(a1,a2) = 2 a1 · 3 a2 . is f one-to-one? onto?

Which of the following is the rational exponent expression of 6 root f

Bismuth-210 is an isotope that radioactively decays by about 13% each day, meaning 13% of the remaining bismuth-210 transforms into another atom (polonium-210 in this case) each day. if you begin with 233 mg of bismuth-210, how much remains after 8 days?

In the diagram below, tan θ = sqrt 3. what is the value of m?
